I have less than you, but still over 3000 hours and still play pretty much everyday, and do the quests still despite having everything unlocked. I still enjoy it and encourage others to play as well, it's just so much fun, and the team that made it should be proud of what they made.
Like @stukapooka I feel it's the best of the 3 shooters. GW is great too, but not as replayable, although I'd love to see those maps brought to GW2. BfN's free roam regions were fun at first, but then felt 'done' so once I maxxed out everything there, I stopped playing. GW3 is still my dream, but better support for GW2 would be fantastic!
